Problems solved by technology
The special seedling assembly blocks of the current rice transplanter use single-layer seedling trays to raise seedlings, and the seedling trays are separated before being delivered to the rice transplanter to obtain the seedling assembly blocks. In order to pursue integrity, an overly thick soil layer is used as the root of the seedlings. In this way, the weight of the seedling assembly block affects the quantity speed of seedling transshipment and mechanical transmission; but, if the root matrix layer of the seedling assembly block is made too thin, its integrity is difficult to guarantee, and the seedling assembly block is often in transit. Cracks and shedding occurred during the transmission process with the machine, which caused a gap in the field for transplanting rice seedlings, and the final result was a reduction in rice production.

Embodiment Construction
[0013] Below in conjunction with accompanying drawing and an embodiment further illustrate double-deck rice seedling raising tray.
[0014] figure 1 Showing a double-layer rice seedling tray The plane structure diagram of the first layer of polyembryonic nest plastic tray (1), this figure is only a part of polyembryonic nest plastic tray (1), and the structure of other parts is also the same. figure 1 Many densely packed small embryo nests (3) are evenly, neatly and regularly arranged and distributed on the plastic plate. The surface diameter of each small embryo nest (3) is only about 0.6 centimeters, and each small embryo nest (3) can only accommodate one or two seeds. Embryo fossa (3). Rice seeds will germinate into seedlings in these small embryo nests (3), and the obtained seedlings are also arranged regularly, which is beneficial to the accurate and rapid clamping by the manipulator of the rice transplanter.

Disclosed is a double-layer rice seedling raising tray. A multi-embryo-nest plastic plate of fixed shape is arranged on the first layer, a polyethylene film layer connected with roots of rice seedlings is arranged on the second layer, round holes are formed at positions of the polyethylene film layer, which correspond to embryo nest positions of the plastic plate, and a connecting line composed of a plurality of needle holes exists between two adjacent round holes. A first-layer plate and a second-layer plate are in a mutually pasted state in a rice seedling raising process, before rice seedling transplanting, rice seedlings and rice seedling plates are separated, and the second polyethylene film layer breaks away from the first multi-embryo-nest plastic layer to be located on a rice seedling gathering block, so that the rice seedling gathering block cannot rot easily, transport and mechanical transplanting are easy, and the production efficiency is improved.
Description
technical field [0001] The invention relates to the manufacturing technology of special seedling trays for rice transplanters, and belongs to the field of agricultural technology. Background technique [0002] When the rice transplanter performs transplanting work, there must be a continuous supply of aggregated seedlings, and these aggregated seedlings must have integrity and the thinness of the root matrix layer, so that the seedling aggregates can achieve the best combination from the number and weight of seedlings. , it is easy for the seedlings to be transported and transported mechanically, so as to achieve the highest efficiency and benefit of modern mechanized rice planting. The special seedling assembly blocks of the current rice transplanter use single-layer seedling trays to raise seedlings, and the seedling trays are separated before being delivered to the rice transplanter to obtain the seedling assembly blocks. In order to pursue integrity, an overly thick soil...
